Hi everyone. Just looking for any ideas from anyone who's upgraded the factory headlights to LEDs on a 1990 gnc jimmy? It had ge h4701 in the low beam position I believe... They worked pretty good back in the day with the relay to keep both on at high beam selection. Burning out now, and I live very rural now, so any ideas would be great! TIA!

I run the LMC housings and diode dynamics SL2 LED in both the high beam and low beam. the low beam bucket needs to be trimmed a little bit at the 6 o'clock position. get them aimed properly and you will have plenty of light.

Here's a very good thread for some great information on the topic:

I have some suggestions to get the best possible light from those tiny lamps.
